Abstract
A method for calibrating a thermometer is disclosed. The thermometer comprises a primary temperature sensor for determining the temperature of a target. The thermometer also comprises a reference temperature sensor positioned proximate to the primary temperature sensor and being responsive to an extraneous temperature affecting the primary temperature sensor. One calibration method calibrates the reference temperature sensor. This calibration can utilize a non-electrically conductive liquid bath for temperature control. Another calibration method calibrates the reference temperature sensor and the primary temperature sensor.
